Embodiment
Online traditional copy guard method fado prevents user from carrying out replicate run at webpage, but user cannot be stoped to check webpage source file, and user still can by checking that the method for webpage source file is easy to just obtain required text from source file.
In order to solve the problem, The embodiment provides a kind of webpage Chinese version information protecting method, device and system.Browser client, after sending web-page requests information to server, at server side the text mixing in webpage, namely upsets the order of character arranging in each section of text, mixing method be encrypted with mixing after webpage be together transferred to browser client.Browser client is resolved and layout after receiving webpage normally, text is also mixing when the storage inside of browser, but the mixing rule of giving by server when showing text display carries out back mixing row to text, and the text that user sees is normal sequence.User is when copying a certain section of text, and the text obtained from browser storage inside is also mixing.
Hereinafter will be described in detail to embodiments of the invention by reference to the accompanying drawings.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.
First by reference to the accompanying drawings, embodiments of the invention one are described.
Embodiments provide a kind of webpage Chinese version information protecting method, idiographic flow as shown in Figure 1, comprising:
Step 101, for client combination requirement request information, except original web-page requests information content, in web-page requests information, also comprise encryption related information.Take such as RSA Algorithm as encryption method, client should generate PKI, and is combined in web-page requests information by PKI and sends to server.
Step 102, user end to server send web-page requests information;
Step 103, server receive web-page requests information, comprise normal request content and the encryption related information (as PKI) of browser client in this web-page requests.
Step 104, server are according to the Content Organizing web data of web-page requests information.
Step 105, server generate mixing algorithm, and mixing algorithm is a kind of method sequences of text upset.
A kind of mixing algorithm of Fig. 2 for using in step, it should be noted that the algorithm that can reach and text be upset object is all in protection scope of the present invention, the embodiment of the present invention is not construed as limiting this.
Below in conjunction with Fig. 2 explanatory text mixing process:
Step 201, the block text taken out in webpage, institute's text of getting should in a label;
Step 202, select a mixing algorithm, if the maximum length of arranging of mixing algorithm is L, if this block text length is N, and N is greater than L, then text is divided into some sections (being set to M section), front M-1 segment length is all L, and final stage length is less than or equal to L;
Step 203, taking-up first paragraph text;
The text size that step 204, basis are taken out calculates the mixing algorithm under this length, and Fig. 3 enumerates a kind of mixing algorithm by mapping relations, and mixing mapping relations can be expressed as expression formula:
F (n)=m, 1≤n, m≤Lm ∈ Zn ∈ Z and F (n
1) ≠ F (n
2), n
1≠ n
2
Wherein n is the position at a certain word place in original text block, and m is the position at this word place after mixing.
As shown in Figure 3, text size is 13, and maximum mixing length is 8, text need be divided into two sections, and first paragraph length is the 8,2nd segment length is 5.
The word 301 of first paragraph is " I wants one section of text to enter ", and length is 8, just consistent with maximum mixing length, and mapping relations are 303.After mixing, word becomes " my text of section want into one ", as illustrated at 302.
2nd section of text is " the chaotic sequence of row ", and length is 5, is less than 8, first will find out the mixing mapping relations that length is 5.As shown in Fig. 3 shown in 304, remove F (3), F (4), F (7), and sequence number is rearranged obtain the mixing mapping relations that length is 5, as shown in 305.Mapped by mixing and can obtain the text after mixing for " sequence of walking randomly is mixed ".
Step 205, by mixing algorithm, mixing is carried out to text;
Text does not take, and takes off one section of text, and to step 204.Until full text takes.
Step 106, complete text mixing.During text mixing, text is got by label piecemeal, as text below, each p label is a block text, 3 block texts to be divided altogether to carry out mixing: " although some reasonable requests that <p> developing country proposes all are not met; China's team represents, regardless of negotiating progress, green low-carbon road for development all will unswervingly be walked by China.</p>
<p> is according to China's team's introduction, the three large problems that this conference is all paid close attention to each side--Durban platform process, loss compensation for loss and damage mechanism, bankroll problem have finally made decision, achieve everybody and are all unsatisfied with but all receptible achievement.</p>
This meeting of <p> is held on the 11st, closing in original 22 days, but because in the key issues such as reply climate change cardinal rule, loss compensation for loss and damage mechanism, fund, developed and developing countries has huge arguement, conference has to consult continuously, is postponed until closing evening on the 23rd.</p>”。
Step 107, mixing algorithm to be encrypted, such as rsa encryption.
Step 108, middle by the web data after mixing with encryption after mixing algorithm combine.
Mixing algorithm after web data and encryption sends to client by step 109, server.
Step 110, client receive the web data of server transmission and the mixing algorithm after encrypting.
Step 111, client start analyzing web page data, and the data after being parsed exist in dom tree, text wherein or mixing text.
Step 112, client are decrypted mixing algorithm.Back mixing row algorithm is obtained as used the private key of RSA to be decrypted.
Figure 4 shows that the citing of a kind of back mixing row algorithm, mixing word reverted to former sequential algorithm all can be used as back mixing row algorithm as long as it should be noted that to reach, the embodiment of the present invention is not construed as limiting this.
Back mixing discharge method shown in Fig. 4 is specific as follows:
Step 401, the one section of text taken out in webpage, institute's text of getting should in same web page tag;
If step 402 text size is N, and N is greater than L(L, and to be that mixing algorithm is maximum arrange length), then text is divided into some sections (being set to M section), front M-1 segment length is all L, and final stage length is less than or equal to L;
Step 403, taking-up first paragraph text;
Step 404, calculate the mixing mapping relations under this length according to the length of one section of text of taking out;
Step 405 calculates anti-mapping relations;
Step 406, penetrate relational file by reflection and carry out back mixing row, the text after mixing is reverted to original text;
This step is concrete as shown in Figure 5, and back mixing row's mapping relations and mixing mapping relations are inverse function relation, are expressed as follows:
G(m)＝F
-1(n),1≤m,n≤Lm∈Zn∈Z
Also need text segmentation when back mixing is arranged, as shown in Figure 5 example, character length is 13, need be divided into two sections, and first paragraph length is the 8,2nd segment length is 5.
The word of first paragraph is " my text of section want into one ", and the mixing mapping relations obtained from server for Fig. 5 shown in 503, then can show that anti-mapping relations are as shown in Fig. 5 504.
Can obtain back mixing row text by anti-mapping relations is " I wants one section of text to enter ".
The word of second segment is " sequence of walking randomly is mixed ", text size is 5, mixing mapping relations (Fig. 5 shown in the 505) length obtained from server is 8, then need to take out the mixing mapping relations that length is 5, as shown in Fig. 5 shown in 505, remove F (3), F (4), F (7), and sequence number is rearranged obtain the mixing mapping relations that length is 5, as shown in Fig. 5 506, then to calculate length be 5 back mixing row's mapping relations (in Fig. 5 507 shown in).Back mixing row text can be obtained for " the chaotic sequence of row " by anti-mapping relations.
If text does not take, take off one section of text to step 407, and to step 404.Until total data takes.
Step 113, client carry out layout to webpage, store (Render as webkit sets) Chinese version and also carry out layout with mixing, carry out back mixing arrangement office when final text shows to text by mixing algorithm at browser layout rendering data.Because text is always the arrangement of mixed sequence in browser clients end memory, therefore user is when copying the text on webpage, can only obtain the text of mixing.
